Clean Cities Coalitions 2019 Activity Report
5/6/2021
Clean Cities coalition activities resulted in an energy use impact (EUI) of over 1 billion gasoline-gallons equivalent (GGE), comprised of net alternative fuels used and energy savings from efficiency projects, in 2019. Participation in vehicle and infrastructure development projects remained strong, as did alternative fuel use and resulting overall EUI. Clean Cities coalition activities reduce emissions as they impact energy use. Coalition-reported activities prevented nearly 5 million carbon dioxide-equivalent tons of emissions (only greenhouse gas [GHG] emissions are reported here; criteria pollutants and other emissions are not included in this report). Coalitions were successful in securing project grant awards from numerous (non-DOE) outside sources. For other Federal, State, and local agencies and private sector foundations, see funding section on page 24. The 82 project grant awards in 2019 generated $225 million in funds from coalition members and project partners along with $9.5 million in DOE grant funds. Coalitions also collected $1.2 million in stakeholder dues and $1.6 million in operational funds from host organizations. In macro terms, this supplemental funding represents nearly a 6:1 leveraging of the $38 million that was included in the VTO Technology Integration budget in Fiscal Year 2019. Clean Cities coordinators spent nearly 136,000 hours pursuing their coalitions' goals in 2019. The average coordinator is quite experienced and has held his or her position for at least eight years. Coordinators logged more than 3,525 outreach, education, and training activities in 2019, which reached an estimated 23 million people.

Comprehensive Total Cost of Ownership Quantification for Vehicles with Different Size Classes and Powertrains
4/1/2021
In order to accurately compare the costs of two vehicles, the total cost of ownership (TCO) should consist of all costs related to both purchasing and operating the vehicle. This TCO analysis builds on previous work to provide a comprehensive perspective of all relevant vehicle costs of ownership. This study considers vehicle cost and depreciation, financing, fuel costs, insurance costs, maintenance and repair costs, taxes and fees, and other operational costs to formulate a holistic total cost of ownership and operation of light- and heavy-duty vehicles. For each of the cost parameters, researchers performed extensive literature review and data analysis to find representative values to build a holistic TCO for vehicles of all size classes.

Assessment of Prospective Mileage-Based Fee System to Replace Fuel Taxes for Passenger Vehicles in Pennsylvania
3/1/2021
Historically, transportation infrastructure in the United States has been funded through a per-gallon fuel tax levied at the state- and federal-levels. The federal fuel tax has remained constant over the last thirty years, even as road construction and maintenance costs have risen steeply in that time. This funding gap is widened by advances in hybrid and electric vehicle technology, which have significantly improved fleet fuel-economy and reduced revenue from fuel tax. To address this, an increasing number of jurisdictions are considering programs where vehicles are taxed per-mile traveled, rather than per-gallon of fuel consumed. These mileage-based user fees (MBUFs) could replace federal and state fuel taxes and reduce the deficit in transportation infrastructure funding. This report develops high-resolution estimates of annual vehicle miles traveled (VMT) per vehicle aggregated at the state, county, and zip code level. Based on these estimates of VMT and fuel economy, researchers estimate the annual cost to vehicle owners of the existing fuel tax, and compare this cost against the cost of MBUF’s, at various rates.

U.S. Airport Infrastructure and Sustainable Aviation Fuel
2/26/2021
Worldwide, aviation accounts for 2% of all manmade carbon dioxide emissions and 12% of all transportation CO2 emissions In 2018, the U.S. accounted for 25% of the world jet fuel consumption and 21% of global enplanements. Airports and airlines are considering alternative fuel to meet environmental and sustainability goals and mandates. Sustainable aviation fuel (SAF), made from non-petroleum feedstocks, has the potential to significantly reduce emissions from air transportation. SAF must be blended with petroleum based jet fuel prior to its use in aircraft. This report explores background information on jet fuel use, quality standards and best practices, airport infrastructure, and options for delivering SAF to airports.
